The reapers have returned from dark space. With Earth under attack and the mass relays in a state of chaos from refugees and the councils fleet engaging reaper forces the galaxy is a mess. The outcome is unknown, the warfare is devastating. The galaxy will never be the same.

Its based on perspective, the diagonal angles that the deviant art picture shows make it seem like it is longer, the same way that looking down the barrel of a gun may make it seem a tad bit longer. if you look at the horizontal shot (2nd from the top left) then you can see it is indeed shorter than the angled shot right below it. Trick o' the eyes mate.

On another note, just started watching battlestar galactica again because of your profile picture Lockerd.
